Figure 2: Krone Connections

12 | ASD774-D


4.1 Thermal Management Alarms

Alarms are given for fan failure, sensor failure and over temperature (60°C).

Fan Failure Alarm:

If the speed of any fan drops below 70% of the speed of the other fans, the speed demand will increase to

maximum speed (approx. 4100RPM dependent on supply voltage and load). A General Alarm will be

indicated by de-energizing the Alarm 1 General Alarm relay and changing the LED to RED.

Open / Short Circuit Temperature Sensor Alarm:

If the thermistor connected to the input Temp 1 is detected as either being open or short circuit, then the

fans will operate at the normal high-speed of 4100 RPM and general alarm will be indicated by de-

energizing the General Alarm 1 Relay and changing the colour of the LED to flashing RED.

High Temperature Alarm:

If the temperature detected by the sensor connected to input Temp 1 reaches 60°C the controller will

indicate a High Temperature Alarm by opening the Normally Closed contacts of the Alarm 2 Relay and the

LED will flash RED/GREEN. The High Temperature alarm will be turned off if the temperature drops to 57°C.

In the event of multiple alarms, the controller will prioritise them as follows:

1. Fan Failure as indicated by a continuous RED LED.

2. Temperature sensor failure as indicated by a flashing RED LED.

3. Filter alarm as indicated by a flashing AMBER LED.

4. Over temperature as indicated by a RED/GREEN flashing LED.

In the event of a controller failure such that there is no output from the microcontroller the fans will operate

at maximum speed (approx. 4100RPM) and the General Alarm relay will be de-energized. There will typically

be no LED indication. In this unlikely situation, the over temperature and under temperature alarms will not

give an alarm indication.

11 Appendix B – Paint Specifications

ASD002-F SUMMARY: Specification of paint process and paint finish excluding colour. Leatherette finish 80 Microns.

The components and assemblies are to be coated by powder coating on all faces. The powder coating process must be approved by CommScope Design and Integration UK. The powder must be polyester based and approved by CommScope Design and Integration UK. Unless otherwise stated the powder coat finish after baking will always be a minimum thickness of 80 microns. This applies to all components and assemblies. Colours will be specified at point of order and are listed on enclosure painting lists. The finish must meet the following specification:

1. Impact resistance – ASTMP 2794 to 60lbs 2. Scratch resistance – BS 3900 PART E2. The cabinet finish shall resist a sharp point weighted to 4.5 kg 3. Coating adhesion – BS 3900 Part E6, Cross hatch 4. Light resistance – QUV O metal to 200 hours 5. Salt spray - Pass ASTMB 177 6. Sulphur Dioxide – BS 3900 Part F8 exposed for 250 hours. There shall be no colour change, softening,

blistering or loss of adhesion of the coating.

The gloss level for external surfaces is 60%, Leatherette

The bare component’s base material will be pre-galvanized mild steel, aluminium or Stainless Steel, according to drawings. Ink used by steel suppliers to identify sheet should have been removed when the parts are supplied for painting, any remaining ink must be removed before coating. It is expected that the coater will be able to paint parts to the agreed standard all over without modifying the parts, i.e. no additional holes will be included to hang the parts unless a written concession to do so is given to the coater from CommScope Design and Integration UK. Where Rivnuts, PEM’s or threaded studs are present, the threads must be masked off before coating.

15 Appendix F – Fitting to Existing Huawei Root THIS INSTALLATION DOCUMENT IS FOR GUIDANCE ONLY, SITE SPECIFIC CONDITIONS OR BUILD

GUIDANCE IS TO TAKE PRECEDENCE

Refer to I-100353 for additional guidance.

Figure 30: Transfer Plinth Installation

An additional Huawei 3900A root must be installed aligned with existing roots both vertically and

horizontally and butted up to existing roots with no gap or ground materials between. It is strongly

recommended that the transfer plinth is fastened to all three Huawei 3900A roots before concrete is poured

and cured to ensure alignment of the roots.

35 | ASD774-D


Figure 31: Duct Positions (Huawei)

Installing Root:

1. Align the transfer plinth on the roots with the slanted profile at the back. The transfer plinth should

be butted up against the existing Huawei cabinet or as close to it as possible. The transfer plinth is

20 mm narrower than the three roots so expect to see a small amount of spare root visible at the

right of the CommScope Bowler cabinet. Align the slots at the rear of the transfer plinth with the

holes in the top surface of the Huawei 3900A roots.

2. Place rectangular washers provided in the fixing kit over each slot at the rear of the transfer plinth

and insert a bolt through the special washer, transfer plinth and root.

3. Where the bolt emerges from the underside of the root top, add a flat washer, followed by spring

washer and thread the nut on to retain. Do this for all the rear fixing points and hand tighten only.

4. Repeat the process on the front slots of the transfer plate then tighten all the bolts another ½ turn

with a pair of 24 mm spanners.

5. Pour concrete and allow to cure for a minimum of 24 hours. The concrete inside the cabinet base

should be a minimum of 60 mm below the top of the root and sealed with a 2mm bitumen coating.

36 | ASD774-D


Installing Transfer Plinth

1. Remove the transfer plinth.

2. Apply a liberal bead of silicone sealant (supplied with the CommScope Bowler cabinet) to the

perimeter of the roots’ top surface.

3. Align the transfer plinth as described earlier.

4. Fasten the transfer plinth down to the roots as described earlier. Tighten the fasteners to 200 Nm.

5. Apply a neat bead of sealant round the outside of the transfer plinth at the joint with the root.

Installing Cabinet:

1. Place a liberal bead of sealant supplied on the top face of the transfer plinth.

2. Lift cabinet into final position.

3. The cabinet is to be secured to the transfer plinth using the 18 off M10 set screws supplied. These

are fitted with a large OD washer inside the cabinet (upward facing face) and a lock washer on the

underside to the face of the transfer plinth. Tighten M10 nuts and set screws to approximately

50 Nm.

4. Apply a neat bead of sealant round the outside of the cabinet at the joint with the transfer plinth.

5. Check that door opens and closes correctly. Shim the cabinet if required using the shims provided in

the fixing kit.

6. Following installation of all cables through the ducts, seal the ducts

7. Close and lock the cabinet door.

Figure 33: Duct Positions (Ericsson)

Installing Root:

1. Check clearances when positioning near existing structures, 100mm gap must be provided at rear.

2. Excavate hole size of 2742 x 800 to accommodate both roots. Depth to suit local ground conditions.

3. Position ducts in approximate positions as indicated.

4. Infill the hole with compacted hardcore at least 150mm deep.

5. Place each end of the root on sand and position so approximately 20mm of the root protrudes

above ground level.

6. Top surface of the root must be level ±2mm in all directions. Pack under ends if required.

7. Infill with concrete inside and outside of the root.

8. Concrete to be left to set a minimum of 24 hours before fitting the cabinet.
